Title: Improvements in or relating to the manufacture of glass in sheet form
IPC: C03B25/12
Filed: 1961-05-12
Abstract: 965,001. Annealing glass sheets. PILKINGTON BROS Ltd. May 12, 1961 [May 20, 1960], No. 17442/61. Heading C1M. In the annealing of sheet glass drawn upwardly from a molten body of glass in a drawing chamber through an annealing tower, the glass sheet is cooled variably across the width of the glass by the introduction of a gaseous fluid such as air at the lowest level of the tower so that the fluid flows upwardly, and at each point of admission the volume and overall temperature of the fluid is adjustable. Sheet glass 6 drawn upwardly by rollers 3 from a molten body 7 of glass past coolers 8 in a drawing chamber 1 passes between catch pans 5 to the annealing tower 2 which has the usual baffles. In the simplest form shown in Fig. 2, two tubes 9 on each side of the sheet 6 are secured in apertures 10 in the end walls of catch pans 5 as by a metal collar each tube 9 being separately adjustable by a set-screw for the extent of penetration into the tower. They may also be adjusted angularly when a slotted tube 9 is used, as in Fig. 6. The collar may also be arranged to allow tilting of the tube 9 in a vertical plane. Normally, the outlet aperture 11 will reach about one-third of the width of the sheet. The inlet aperture 12 has a damper 13 to regulate the amount of air entering the tower and the air may be heated as by a circular gas burner 14 inside the tube. Each tube 9 may be replaced by a pair of concentric tubes as shown in Figs. 7 and 8, the outer tube 15 having a straight slot 16 and the inner tube 17 having a wider slot 18 offset at the middle. Rotation of tubes 15 and 17 relative to each other gives a variety of openings at different points along the tubes. A circular burner 20 and fixed helix 21 give well-mixed, heated air and the outlet aperture 11 has a damper 22 controlled by a rod 23. A number of variations of the shape of the slots for the tubes 15 and 17 are disclosed. Direct contact of the air with the rising sheet is avoided by the positions of the slots and in addition, the catch pan 5 may have an upward flange or the tube 9 may have an adjustable plate. The edges of the sheet may in addition be heated by an adjustable burner located in the end walls of the catch pans 5.
